P-35/37 / BAR LOCK

Radar Station or Radio-location Station (RLS) P-35 has a large tactical radius. It insures a circular scanning of the air space, detects the planes which are located in its operational zone and calculates their coordinates. The station P-35 has the following basic tactical and technical characteristics: Maximum range, depending on the type of plane and height of the flight-from 150 to 350 km. For example, the plane TU-104 which flies at an altitude of from 8,000 to 10,000 meters is detected at a distance of 350 km; the scanning zone: in altitude-up to 25,000m, in angle of location-up to 30 degrees; errors while determining the coordinates: in distance plus of minus 500m, in azimuth plus of minus 0.5 degrees; partitioning ability: in distance-500m, in azimuth-1.5 degrees; time for one circular scanning of the space is 20 or ten seconds, in accordance with a speed of ratation of the antenna-3 or 6 turns per minute. RLS P-35 has 6 channels. The 6 channels have frequencies in the the centimeter range.
